  (PDF) Smithsonite Flotation from Zinc Oxide Ore using Alkyl …

  Separating oxidized zinc minerals from flotation tailings is always a challenge. In this study, a flotation tailing from Wulagen zinc mine in China (Zn grade < 1%) was processed using froth flotation with combinations of amines (OPA 10, OPA 1214, OPA 13, DDA) and Na2S to study the effects of these amines on the zinc recovery as well as their interactions with other …

  Study on the pre-treatment of oxidized zinc ore prior to flotation

  The pre-treatment of zinc oxide bearing ores with high slime content is important to ensure that resources are utilized optimally. This paper reports an improved process using hydrocyclone de-sliming, dispersion reagents, and magnetic removal of iron minerals for the pre-treatment of zinc oxide ore with a high slime and iron content, and the benefits …

  Mixed sulphide–oxide lead and zinc ores: Problems and solutions

  201181 · Mixed sulphide–oxide lead and zinc ores are most often found in the transition, and occasionally in the oxidised, zones of lead–zinc ore-bodies. They are of great importance because there are numerous unexploited or abandoned reserves of these ores in the world. However they present difficulties for conventional mineral processing due to ...

  Investigation on matching relationship between surface characters …

  2021520 · Abstract There are multiple factors that affect flotation separation performance. However, most studies only focus on the influence of a single factor, and neglect to study matching relationships among multiple other factors. In this paper, improved separation performance of zinc oxide minerals from quartz was achieved by modifying the …
